SPECIFICATION forming part of -Letters Patent No. 706,883, dated August5, 1902.

Application filed August 19, 1901. ASerial No. 72,505. (No model.)

To all zutrmt it may concern:

Be it known that I, WILLIAM FRANKLIN CAHOON, a citizen of the UnitedStates, residing at Skinnersville,in the county of Washington and Stateot' North Carolina, have made certain new and useful Improvements inOultivators, of which the following is a specification.

Myinvention is an improvement in cultivators having for an object, amongothers, to provide bent teeth which operate in connection with theframe, so the teeth can be adjusted to throw to or from the plant, asmay be desired; to afford facilities for the proper adjustment of theteeth independently of each other; to produce an implement that willthoroughly pulverize the soil before it is shoved up to the plant, inthe use of which implement the amount of soil thrown to the plant can bevaried, increased, or decreased Without the use of eXtra teeth; to soshape the teeth that they will not ride the earth when hard places areencountered; to provide for adjustment so the teeth can be moved on theframe vertically or horizontally, and to so shape the frame that it canbe opened or closed, and thus avoid loss of time necessary for movingthe teeth.

The invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described and claimed.

In the drawings, Figure lis a side view, and Fig. 2 a top plan View, ofa cultivator embodying my invention; and Fig. 3 is a detail view of thehandle-stand. Fig. 4 is a side view, and Fig. 5 a face View, of one ofthe teeth provided at one end with a curved shovel. Fig. 6 is a detailperspective view of the keeperclamp for the inner ends of the adjustableteeth-supporting frames. Fig. 7 is a detail sectional view on about line7 7 of Fig. 2, illustrating the means for clamping the inner ends of theteeth-supporting frames of the cultivator. Fig. S is a detail top planview illustrating one of the handle-supporting uprights and the meansfor clamping it to the handle. Fig. 9 illustrates in detail one of theclamping-blocks shown in Fig. 8. Fig. 10 is a detail perspective View ofone of the clamp-blocks for use in securing the teeth to thetooth-supporting frame; and Fig. 11 is a detail perspective View of oneof the teeth and the means for securing the same, all of which will behereinafter described.

In constructing my cultivator I employ the beam A. The handles B arepivoted at their front ends at B to the beam A and lie on opposite sidesof said beam and arepressed apart near their rear ends by the distancepiece or bar B2. These handles B are supported from the beam A, near therear end of the latter, by the stand O. This stand O is shown in detailin Fig. 3 of the drawings. This stand O is bent from a rod of metal,having at its middle the cross portion C to it upon the beam A andprovided in said portion C with a notch C2 `for engagement by thehook-bolt O3, which operates to secure the stand iirmly ot the beam, asbest shown Fig. 7. The stand C has the upright portions or rods O4,which extend along the inner sides of the handles B and are secured tothe latter by the hookbolts C5, which pass through the handles and aresecured by nuts, so they can be tightened up as desired. Tooth-blocks CG(shown in detail in Fig. 9) are arranged between the upright rods O4 andthe handles and are provided with the curved toothed socketsy shown atO7, against which the upright portions C4 of the stand C are clamped bythe hook-bolts C5 to insure the clamping of the handles in the desiredposition upon the upright portions of the stand, as desired. By thedescribed construction the handles may be adjusted to and held in anydesired position.

Near its rear end the beam A is provided With the keeper-box D. (Shownin detail in Fig. 6 and applied in Figs. l and 7.) This keeper-box D hasthe lugs or flanges D',Which lap beneath the beam A and are perforatedfor the passage ot the bolts by which it is secured to the under side otthe beam, as shown in Fig. 7. It will be noticed that the hookbolt O3for securing the handle-stand C to the beam A is also arranged to securethe keeperboX D at the front side of the latter, as best shown in Fig.7. This box has a threaded opening at D2, through which it is entered bythe clamping-screWE,Which may be operated to bind the portions F of thetooth-supporting frames in the keeper-box D and so hold the said framesin any desired adjustment. The

frames F are provided at their rear ends with IOO the portions F', whichextend laterally Within the keeper-box D, as shown in Fig. 2, so theymay be engaged by the clamp E for the purpose of holding the frames F inany desired adjustment. At their front ends the frames F are secured atF2 to the beam A, preferably by means of a bolt, as shown, upon whichthe frames can be swung in and out, as desired. The frames are alike,except that they are made rights and lefts or may be exactly alike andturned side for side to suit them for eitherside of the beam A and areeach formed with the outwardly-extending portions F3 and F, arranged onein rear of the other and inclined to the direction of draft andconnected at their outer ends by the connecting portion F5, the frontand rear laterallyextending portions F3 and F4 being parallel with eachother, as best shown in Fig. 2. By the described construction it will benoticed that the frames F can be adjusted upon a securingbolt at F2 inor out at their rear ends and secured in any suitable adjustment by theclamp E, before described, the keeper-box operating to receive the endportions F of the frame and aiding in the clamping thereof, as desired.The teeth G are secured to the parallel vfront and rear portions F3 andF4 of the frames F, so they can be adjusted either vertically orrotatably to set their points G or their shovels H at any desired heightand at any desired angle to the plants. In securing this feature of myinvention I provide clampblocks I for each tooth G, such blocks I beingshown in detail in Fig. lO and being provided near theirupper and lowerends at their rear side with lugs I to lap above and below the bars ofthe frames, as Will be understood from Figs. 2, 10, and l1, and are alsoprovided at their opposite sides with grooves I2 for the arms of the U-shape bolts J, which are passed around the tooth, and with the armslying within the grooves I2, and thence through plates J on the rearside of the trame-bars and secured by nuts, as shown. The clamp-blocks Iare provided in their outer faces with the upright curved grooves I3,which are toothed, as shown in Figs. 2 and 10, so the teeth can beclamped securely by the bolts J, as will be understood from Figs. l0 and1l.

The teeth G are provided with the points G' at one end and are curved atG2 at their other end to receive the shovel H, which latter is securedby the bolts I-I, slotted openings being provided at H2 to provide for acertain adjust-ment of the shovel, as may be desired.

It will be noticed that the seat G2 and the blade H are curved ondifferent arcs, leaving a space between them, into which the blade maybe drawn when the bolt H is tightened, giving a solid bearing tor theshovel or blade I-I, as desired. It will also be noticed that the bladesor shovels I-I may be reversed end for end when Worn. t

By the described construction it will be noticed the cultivator-teethmay be turned end for end Whenever desired, can be adjusted up or down,and turned at any angle to the plan ts to throw the dirt toward or fromthe plants to any desired degree. The construction is simple, and eachportion of the cultivator can be readily adjusted for the purposesdescribed.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. The combination in a cultivator of the tooth-supporting frame-bar,the clampingblock having an upright curved groove for the tooth, andprovided at its opposite ends with lugs or ears to overlap theframe-bar, and at such ends With grooves for the clamping-bolts, thetooth, and the U-shape clamping-bolts tting around the tooth and in thegrooves of the clamping-block, and securing the tooth andclamping-blocks in connection with the frame-bar, substantially as setforth. 2. In a cultivator, the combination o'f the beam, the handles,the keeper-box applied to the beam near its rear end, the bolts securingthe said keeper-box to the beam, the handlesupporting stand held to thebeam by one of said bolts, means securing the handles to the uprightportions of said stand, the tooth-supporting frames having at their rearends portions tting Within the keeper-box, and clamp devices forsecuringr said portions in the keeper-box, substantially as set forth.

WILLIAM F. CAHOON.
